Since they were first introduced just over 20 years ago, robot vacuums have become one of the most popular cleaning devices on the market. Efficient, convenient and practical, they are truly capable of making your life easier and your environment healthier.
Without a doubt, one of the most notorious robot vacuum brands is iRobot. Over the years, the manufacturer’s Roomba line has positioned itself as the most recognizable name in the world of robotic vacuums.
First, it will provide basic information about each of these robot vacuums. After that, it will provide thorough comparisons between them. Hopefully, all this information will help you choose the perfect one for you.
About These Roomba Robot Vacuums
Before moving on to describe each of the four Roomba robot vacuums that are featured in this article, it would be wise to spend some time talking about the things they have in common. Being manufactured by the same company, all four of them share a lot of characteristics.
- Of course, all these robot vacuums rely on a brushing and suction system to remove dust, dirt and debris from the floor.
- To do this with efficiency, they use a multi-room navigation system that, unlike that of other robot vacuums, is not pseudo-random but logic-based.
- In addition to this, all these Roomba models have some form of dirt detection capabilities to help them function more effectively.
- To have enough power to clean continuously for several minutes at a time, all these Roomba robot vacuums use a lithium-based battery that is rechargeable. However, the time they are capable of functioning for with a full charge varies according to each model.<.li>
A First Glance – Four Comparative Reviews
1. Roomba s9 – What Does It Have to Offer?
In many ways, the Roomba s9 is the new standard Roomba model. Efficient, effective and very easy to program and control, this device can help you keep your home clean without breaking a sweat. Featuring a 3-Stage cleaning system, this model offers a great deal when it comes to performance. Even better, this type of cleaning system is effective on a variety of surfaces and with a variety of messes ranging from dust to crumbs.
When it comes to navigation, the Roomba s9 is very efficient. After creating a very detailed map of your home, the device will require you to choose which spaces it should clean (and which ones it should ignore). After that, it will promptly get to work, using its dirt detection sensors to figure out what parts it needs to spend more time cleaning.
Unfortunately, the Roomba s9 is not one of the robot vacuum models with the longest battery lifespans. However, its 75 minutes of functioning time are always spent efficiently, often allowing it to finish its cleaning duties before it needs to recharge. When that time comes, like all the Roomba models featured in this article, the s9 will dock itself automatically so the recharging process can begin.
2. Roomba s9+ – What Does It Have to Offer?
In more than one way, the Roomba s9+ is similar to the s9. However, it has a few features that the latter does not have, and it features various enhancements that set it apart from the older model.
Without a doubt, one of the most notorious features that the Roomba s9+ has is its automatic dust bin emptying ability. While most Roombas out there are capable of self-docking in order to recharge, most of them are not capable of emptying their own bins whenever it’s needed (or after every use).
Apart from its bin emptying capabilities, the s9+ has different enhancements that set it apart from its predecessor. For one, its suction capabilities are better. Additionally, its battery’s lifespan is longer, reaching a maximum of 90 minutes. Additionally, due to its employment of a smartphone app, its control capabilities are remarkable.
3. Roomba i7 – What Does It Have to Offer?
Compact, silent and efficient, the Roomba i7 is another great example of what iRobot has managed to pull off with this line of robot vacuums. Like the Roomba s9, it features a 3-stage cleaning system that is remarkably effective. However, being smaller and less powerful than the aforementioned model, the i7 is not as effective when it comes to cleaning carpets and other rugged or textured surfaces.
Despite its effectiveness, the Roomba i7 is surprisingly affordable. Still, it has most of the features you would want out of a robot vacuum. A great example is its automapping control system, a feature that is incredibly useful, particularly when you have preferences in terms of spaces you want to be cleaned and space you want to be left alone.
Sadly, the Roomba i7 does not have automatic bin emptying capabilities. However, it does have automatic docking capabilities for when it’s not working. Additionally, it has dust detection and other capabilities that make it more efficient and effective, reducing the time (and battery life) that it requires to keep your home clean.
4. Roomba i7+ – What Does It Have to Offer?
Being a more updated version of it, the Roomba i7+ is a lot like the Roomba i7. However, it does have some enhancements and additional features that make it worth looking into with more attention. Practical and modern, this device can be a good choice for those looking for something more affordable than the s9 and the s9+.
Like the Roomba s9+, this robot vacuum has automatic dust bin emptying capabilities. Even better, it does not require your input to perform this action. Instead, it automatically empties its dust bin whenever its sensors detect that it is full. What is more, it will simultaneously use this time to recharge its batteries, making itself more efficient.
Although it’s not as powerful as the Roomba s9 or the Roomba s9+, this model is capable of effectively dealing with a variety of substances and debris types that need to be picked up. It should be noted, though, that it’s more compact than those other models, and its motor is also less powerful. As a result, it may have some trouble functioning on thick carpets and other difficult surfaces.
Now that you have a stronger sense of what makes each of these robot vacuums unique, it’s time to go deeper. Before learning how much is a Roomba vacuum cleaner, it’s important to take a look at what its capabilities are.
With that as a goal, we will go over five defining valuation categories for each one of these Roomba products. If you want to find out everything about these four models, keep on reading.
Vacuuming PerformanceRoomba s9 – Despite not being the most powerful robot vacuum of its kind, the Roomba s9 is remarkably efficient when it comes to vacuuming performance. Using a 3-stage cleaning system, it can dislodge and prepare dust, dirt and debris before its suction capabilities have a chance to shine. Like the Roomba s9+, it uses two different brush rolls, each one dealing with a different type of surface. Additionally, it has external side-brushes that can help sweep walls as it cleans. Roomba s9+ – Larger than other Roomba models and featuring a powerful motor, the s9+ is capable of cleaning hard floors and carpets very successfully. Largely, this success has to do with its rubber brush rolls, a couple of features that can quickly accumulate dirt, dust and debris, readying it for suction. In addition to this, the device has a five-blade brush that will help remove dirt and debris from difficult places such as corners. In addition to all this, this Roomba model allows you to control its cleaning strength, allowing you to get rid of difficult stains and other similar problems. Roomba i7 – Despite being the weakest of the four robot vacuums featured in this guide, the Roomba i7 is still reliable and efficient when it comes to its vacuuming performance. In most cases, it’s capable of picking up dust and dirt with no hiccups. What is more, it can suck in small accumulations of heavier and larger pieces of debris such as food crumbs. Even better, unlike most robot vacuums around its price point on the market, it is capable of doing this without spreading pieces around. Roomba i7+ – Despite being smaller than the s9+, the Roomba i7+ features two separate brush rolls. Each of them has a role when it comes to cleaning. While the largest brush roll is meant for cleaning carpets, the smallest one is very efficient when working on hard floors. In addition, the device has a spinning three-blade brush that’s located on its side, allowing it to sweep the edges of walls as it works. Luckily, the device is also capable of automatically detecting the type of surface it’s working on. As a result, it will leave you free to do your own thing while it decides what brush roll it should use for each section of your home.
Bin and FiltersRoomba s9 – Without a doubt, the Roomba s9 has one of the largest collection bins of any Roomba model out there. Perfectly concealed, the 13-ounce dust bin is capable of holding a variety of materials safely and securely. Rinsable, it can be easily cleaned whenever you feel that is necessary. Additionally, it features a large allergen filter that will help keep your house devoid of harmful particles. Roomba s9+ – Much like the Roomba s9, the Roomba s9+ has a large dust bin that can hold up to 15 ounces of material. Unlike the s9, however, the s9+ has automatic dust bin emptying capabilities. Without a doubt, that is a useful feature that will save you a lot of time. Even better, it will prevent you from having to come into contact with the dirt and dust that the device picks up very often. At any rate, though, the robot vacuum’s bin is washable, allowing you to clean it whenever you feel the need to do so. As if all that wasn’t enough, the s9+ automatically bags the dirt for disposal. Roomba i7 – The Roomba i7 does not have the largest dust bin you will ever see. However, it’s large enough for it to handle all the dirt it can find during its 75 minutes of battery life. Unfortunately, this dust bin cannot be automatically emptied by the device. Instead, you will have to do it yourself. Thankfully, however, the process for doing so is relatively quick and easy. As a matter of fact, it only requires pushing a button and taking out the bin. Additionally, the bin is washable. Roomba i7+ – Visible from the device’s side, the Roomba i7+’s dust bin is large and practical. In fact, it is capable of housing the surprising amount of 16 ounces of dirt at any given time. In addition, like the Roomba s9+, the i7+ has self-emptying capabilities, making it extremely convenient. Additionally, the device allows you to empty its contents whenever you want to simply by tilting it over the garbage can and pressing a button.
Battery LifeRoomba s9 – While it does not have the longest battery life you will ever see, the Roomba s9 is efficient enough to make the most out of its 75 minutes of functioning time. Like most modern Roomba models, it will dock itself for charging whenever its battery life reaches dangerously low levels. Unfortunately, its auto-docking capabilities are hindering slightly by its design, which requires it to move somewhat awkwardly and slowly before the process can be completed. Roomba s9+ – With extended battery life, the Roomba s9+ is capable of covering large sections of the floor before having to recharge. When the time to recharge does come, the device will automatically head on to its dock. To prevent problems docking, the s9+ has a charging dock on its base that extends itself to the floor, allowing the device to roll on and off the dock with ease. The charging time for a full charge is two hours. Roomba i7 – Offering up to 75 minutes of battery life, the Roomba i7 is capable of getting a lot of work done before it is required to recharge. Like the i7+, it can clean for up to 75 minutes at a time. However, it takes a bit longer to fully recharge than its plus-signed counterpart. At any rate, however, the device’s recharging process is efficient and quick, and it does not experience problems while trying to dock. Roomba i7+ – The Roomba i7+ has a smart design that allows it to easily dock itself in order to charge. The charging dock is located right underneath the automatic dirt disposal, allowing the device to recharge itself as it empties its contents. Something that this Roomba does differently than its predecessors is that its base inclines automatically whenever the device docks or undocks, preventing it from wobbling and losing precious seconds. Rather notably, this device only takes 85 minutes to fully recharge.
Smart NavigationRoomba s9 – Due to its compact size, the Roomba s9 is capable of fitting under most types of furniture, including coffee tables and raised couches. In order to know where to go, the device uses various sensors, including a dust sensor that will tell it what the most efficient cleaning route is. Additionally, it is capable of detecting obstacles, although not as efficiently as the s9+ or other plus-sign Roomba models. At any rate, however, the device is capable of navigating effectively through complex surface layouts. Roomba s9+ – Using a vSLAM optical sensor that is capable of detecting several obstacles at the same time, the Roomba s9+ can navigate your entire home smoothly and efficiently. Using two treaded wheels, the device will maintain its standing position no matter what kind of obstacles it has to deal with. Additionally, it features four different cliff sensors that will prevent it from falling over the stairs. As if all that wasn’t enough, iRobot gives its customers the possibility of buying a dual-mode virtual wall that can help create either a straight or a halo-shaped barrier that the device will not cross. Roomba i7 – Featuring a persistent mapping technology, the Roomba i7 is capable of navigating its way through your home effectively and efficiently. Using the device’s built-in camera, its mapping technology is capable of recording and storing information about your home’s physical layout, allowing itself to create smart routes when the time comes to make its way through your home. Apart from making the cleaning process more effective, this capability allows the Roomba i7 to perform its job remarkably quickly. Roomba i7+ – Featuring six cliff sensors and an advanced floor tracking sensor, the Roomba s9+ is capable of planning its trajectory very carefully. In fact, it could even be said that this device is strategic in its approach to cleaning your home floors. Even better, it is capable of quickly and efficiently detecting obstacles, including stairs and others that could otherwise cause it to have an accident. Largely, the product’s mapping technology relies on the dual-mode virtual barrier that comes with it. With the flip of a switch, you can create either a straight no-cross line or a protective halo.
Without a doubt, the four Roomba models that are featured in this article are smart, modern, efficient and convenient. As such, all of them are worth looking into.
